Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A tree is composed of ____ connected by edges or lines.
A
Fruit
B
Leaf Node
C
Root Node
D
Nodes
Explanation: 

Detailed explanation-1: -A tree structure consists of nodes connected by edges.

Detailed explanation-2: -The edges of a tree are known as branches. Elements of trees are called their nodes. The nodes without child nodes are called leaf nodes. A tree with ‘n’ vertices has ‘n-1’ edges. If it has one more edge extra than ‘n-1’, then the extra edge should obviously has to pair up with two vertices which leads to form a cycle.

Detailed explanation-3: -Nodes are connected by edges . Each node contains a value or data, and it may or may not have a child node . The first node of the tree is called the root . If this root node is connected by another node, the root is then a parent node and the connected node is a child .

Detailed explanation-4: -It consists of a central node, structural nodes, and sub-nodes, which are connected via edges. We can also say that tree data structure has roots, branches, and leaves connected with one another.

Detailed explanation-5: -Path. In a tree data structure, the sequence of Nodes and Edges from one node to another node is called as PATH between that two Nodes. Length of a Path is total number of nodes in that path. In below example the path A-B-E-J has length 4.
